Primitive package on hackage out of date?

Hi libraries list, It seems that the `primitive` package on Hackage is out of date. The version on github has more functions such as `sizeofArray`, as well as support for SmallArrays. Could the new version be uploaded to Hackage? Or is there a reason why it can't be? The version number is the same for both though (0.6.1.0), so the cabal file should probably be updated first. Twan
